Youtube

Hi, I'm not sure if I'm in the right place to ask this question? My question isn't directly related to computer problems but regarding 'youtube'. If I AM in the wrong place, please excuse me. The problem is this...when I go into 'Youtube', I can play any video clip, but when I go to play a movie, in the first few seconds of play, my screen 'blinks', or flashes two or three times, then for some reason different films (up to 2 or 3) begin to play for a split second, one after the other, and then I get the error message - "an error occurred, please try again later". There's a 'learn more' link, when I've clicked on this, there are various options, all of which, having negotiated, haven't fixed the issue. Please can you give any advice on this? Thank you.
